Abstract:Long-span optical communication technology is an indispensable technology for the construction of backbone communication network in power system.Based on the worst value numeration of restricted attenuation length in optical communication system,this paper analysed the technologies and products that used in long-span optical communication system,highlighted five applications of long-span optical fiber communication technology in power system,calculated the restricted attenuation length of each application,combined with engineering practice,recommended four solutions.The results show that the solutions have the advantages of easy realization and high cost performance.It has reference and practical value for optical communication engineering in power system.
Keywords:restricted attenuation  FEC  EDFA  distributed raman amplification  ROPA
